Hello, everybody! I'm new to this forum, so i might not be in the right place lol

I have an Asus ENGT240 in my rig, but it's old as hell lol and i want to make an upgrade to a Asus HD7770 2GB GDDR5.
My question is: will a 460W psu be enough to power this big guy?


This is my rig:
CPU - Intel Core 2 Quad Q8200S 2.33Ghz @ 2.8Ghz (OC)
RAM - 2x2GB DDR2
VGA - Asus ENGT240 1GB DDR3
HDD - 2x 250GB drives
MoBo - Asus P5KPL-AM


Thanks in advance! :)

Yes, or it must be a real bad one. Power difference between 240 and 7770 isn't that big ( 10W ? )

Is it a generic 430w? If so, no. BTW, why the 2GB version?

Going for the 2GB will i have more performance on the games comparing to the 1GB version?

Uhmmm. On the sticker, its says "Adiance" or "advance".

Want me to tell you the volts and stuff on the rails?

Please tell the amperages on the 12V rail(s) and what connectors it has.

30A on the 12V rail.

1x 20/24 connector to the mobo
1x4pin to the mobo (not molex)
2x SATA
and maybe around 6x molex. No PCI-E 6-pin connector though :/

It will not work then. HD 7770 requires at least one PCIe power connector. Adapters exist for those, but if the power supply doesn't have them natively, those adapters may fry the card.

Really? So why they come with the graphic card if it is that bad?

Well, they can help if you got three power connectors and you need 4th one for 2nd card (let's say card needs one of them). However, when there are no connectors available, there must be a reason why the manufacturer didn't include them: the power supply might not be powerful enough to give power to the graphics card.

Yes. You will need another PSU. That is unless you were to have a couple of SATA splitters, then SATA->molex converters, then molex to 6-pin connectors! LOL. But I believe the HD7750 doesn't require an extra connector?

Uhmm, I see. But the amperage is good, though?

I'm not using any splitters/adapters in my pc. I use whatever comes from the PSU! I have one HDD that uses the SATA power connector and it comes directly from the psu. In fact, the 2 SATA connectors come out seperately from the rest. The only adapter I would use would be the 2 molex to 1 6-pin pci-e connector.

Yeah, if it's true. Like Sinus says ; there's probably a reason for not having a connector.

Though on an other thread i saw someone ( also addict, for whats it's worth )who stated that it would be possible with a molex adapter.

So, who's right ? I dunno, but for the 35 bucks for a new psu i wouldn't risk it.

Well, i dont know. Im not from USA, so i cant use new egg. Maybe i will go for a lower card, like the Asus HD7750-1GD5. What do you guys say about this one?

7750 would run on that psu, no problem. Asus is ok.
August 29, 2012 1:00:15 AM

That's good to know! And card itself? how its performance for a mid price card?
August 29, 2012 1:25:51 AM

Yeah, a lot better lol

Thanks a lot!
