You don't list the hard drive but feel it important to state air cooled PSU :confused:

Manufacturers such as Nvidia are very conservative when quoting power figures to play it safe.
The 400W you recorded at the wall was the AC input whereas PSUs are rated for DC output.
So if your PSU is 90% efficient at that output level the DC output is 360W which gives more headroom.
Dell have control of this system so know what they are doing.

SSD = £220, RAM = £120, HDD = £20, Water Cooler £50 = ~£410.

Not Sure why but the link is not working for me: (Try and copying and pasting into address bar)

I'd only budge if it comes with an actual Alien

On the surface this looks a good deal for a prebuild, that said I still wouldn't touch it with a barge pole if it were my money.

Dell outlet has better deals for this.

I got above with 32gb. Liquid cooled. 500gb nvme drive and 2tb drive for £1370 inc vat and delivery.

wow I just saw the price of memory at the moment. Dam Brexit.

Isn't a 460W PSU a bit too low for a 1080?

Nand isn't the same as Dram, must be a shortage of both.

Memory is not NAND and the shortages are due to the manufacturers reducing capacity as they had an over supply.

No it's not just that. My GTX 1070 says requirements with it with full setup is atleast 500w. A 1080 requirements is 600w or more with full setup. I bought a watt measurer and my system at the time was using 400w.

Some outlet products I've bought are brand new even though they say they're refubished or scratch and dent. One however was definitely used, albeit it for about 6 months based on its service tag history.

Of course it's not...there are other components that draw power, but relating to that build, it's enough. Remember that quality 460W PSU is in most cases better than no name PSU with higher power output

I just can't get my head around how these can be cool and quiet.



Do Dell not use their own generic components anymore?

This unit already comes with the 512Gb M.2 SSD

Would be interested on alternative. Looking to drop about 1500. Happy to self build. Anyone got a recommendation? Would be appreciated thanks

Could you not just buy a better psu or would it not fit in the case?

Lol at the 460w psu

Nvidia claim 180W. They also recommend a 500W PSU. Let's think about that for a moment, the most power hungry part of the system draws less than 2/5ths the PSU's output, so what on earth do they think is in the system to be using 300W? 30 HDDs? Dual 150W xeons?

Their recommendations are really off the mark, and I suspect it's because people buy 1000W PSUs for a fiver and expect them to sustain that output. In reality they'll do a small proportion of that, and that's probably enough for the GPU if they over-estimate massively. People really do that by the way, had a distant family member ask why his PC kept shutting off after a half hour, turns out his 800W PSU could barely sustain 200W, and he had ~300W of load on it.

Both links not working for me?

460w PSU are they having a laugh? This PC would not be functional after a couple hours use on heavy loads. Forget gaming on this thing. Knowing Alienware/Dell it's probably fitted with crappy non-branded bronze quality power unit as well.

Instant replace, making this deal more like £1,400.

This seems bad to me, can't oc processor, only 2133mhz ram and the power supply is bad... I mean pls you could get a much better system for this price.

I get what you're saying but Dell haven't specified the efficiency of the PSU and you need to factor that in. Let's say it's an 80 Plus Bronze at least, that's 368W of pure output. Doesn't matter what nVidia says, real world (see Anandtech) reckons it's around 250W - AMD did this as well, the R9 290 is supposed to pull 250W but is usually 300-320W. That's little over 100W left for the other bits. I'm sure Dell did the maths but that's not a lot of headroom, especially as you don't want to run a PSU at 100% load.

Personally, I agree, cheap high-rated power supplies are a scourge. I used to buy these cheap things but now all my systems have Corsair RM (Gold), HX or AX (Platinum) power supplies in them and I know these are good units.

A 1000W power supply can supply 1000W DC output to the components of the computer, it can draw more than that from the wall. If it were 80% efficient it'd draw up to 1250W from the wall.

250W power draw? Odd, I'm seeing 180W in places like this tom's hardware review of power consumption at the PCI-E socket and extra power connectors. It does spike a lot higher than that, but there's some leeway in dell's PSU, plus most good ones can supply about 100W more than their rating for short bursts so I wouldn't worry.

Would this Gaming rig comfortably suit VR gaming such as Oculus Rift at say it's best settings straight out the box or would there be more work to do to it?

For an extra £20 you can get an unlocked I7-6700K model processor( Which can be overclocked )
http://www.dell.com/uk/p/alienware-aurora-r5-desktop/pd?oc=d00awr530&model_id=alienware-aurora-r5-desktop

Unclockable Model i7-6700 Processor http://www.dell.com/uk/p/alienware-aurora-r5-desktop/pd?oc=d00awr522&model_id=alienware-aurora-r5-desktop

that difference in Processor is at lest £100 to upgrade from I7 to I7K

I don't know whether to go for this or an The XPS 8920 ( No overclocking this processor) desktop http://www.dell.com/uk/p/xps-8920-desktop/pd?oc=cdx89205&model_id=xps-8920-desktop

seems like a better deal than Alienware Aurora newer model Pc cheaper too

I used to lust after AlienWare - until I discovered 3XS computers from Scan. Far better value for money and much better performance from the cutting edge components.

Yes, that was my bad in a rush, a 460W PSU will (should) output 460W DC-side. But personally, and maybe this is just me, but I try not to push my PSUs at full load above about 80-90% maximum output and Dell is cutting it fine here. I think I've been looking at the 'Ti' version...
