My friend managed to get a Reference Sapphire HD 4870 512MB for £20 the other day! BARGAIN!!!


BUT his PSU atm is a Casecom 500w, with not enough ampage to actually run the card....

I was just wondering, what is the cheapest PSU he could get that would run it, it has to be in the UK and it only has to power a Pentium E6300 and 2GB of ram as well..

Tell him he need to upgrade the rest of his rig to get the full power out of that GPU. NEVER CHEAP OUT ON A PSU!!! tell him to buy a nice quality 700W unit and be happy for the next couple years.

That is a bargin, I'd bag a Corsair CX400W and I agree with JonnyFenix, most important part of a rig the PSU.

^^This. That pentium, unless seriously overclocked, will be a massive bottleneck to the 4870 - and you will want to get something like an antec 650 earthwatts.

You see, If I do upgrade down the line, I'd most likely give me stuff to him so he'd get a quad core, so I'm not sure about 400w, what about

Antec Basiq Plus 550W

Dude. Why must you cheap out on the PSU? Its the heart of every rig.Having a cheap PSU is like having a heart of a 90 years old sick man.

Back to the topic, my Seasonic M12ii 430w can power cards from HD4850>4870>gtx460>current HD4890. Its even reported that it can SLI two HD4870. And it cost me 80bucks 2nd hand.

Yeah I know, but he only gets £7 a week so money isn't the best flow for him.... bearing in mind he's still in full-time education...

So a nice 400-500w??

Corsair HX620

5 Year warranty, rock solid quality - job done. Would be well worth saving up for!

EDIT: You can find some great deals on used PSUs on eBay. Provided that you're buying a good quality unit in the first place you shouldn't have many worries about the fact that they've been used. I picked up my Corsair HX620 for £50 and it's been running beautifully. Also, the 1000W PSU I'm running at the moment was free!

He definitely doesn't need more than 400W, that 4870 won't even pull more than 300 at the most with all the other components assuming the PSU is a good build.

If he wants more to future proof then go for it.

Im glad you said amperage and not wattage. I think people put way to much into their wattage rants.
This PSU Wattage calculator puts his system use at roughly 270Ws, recommending a 320W minimum PSU. A good quality 400 or 420 should work out nicely for him.

Erm, quad-SLi 480's won't even get close to just one 1200W psu.

Quad SLI draws just over 1500w so indeed two PSU's would be needed, but I don't think he's EVER going to be drawing that sort of power....

This review shows them using only 1 1200W AX so I'm assuming it gets up to 1000 maybe 1100w at a full load if that much.

Only review I could find on the fly.
