Need some PSU assistance!

Closed
Silcrows

Ok so I purchased a GTX 770 yesterday, it will be arriving tomorrow, however I do not have the required cables to power this. it needs a 6 pin and a 6+2 pin. My motherboard also needs a 4 pin. I have ordered a 2x Molex to 6+2 adaptor but people are saying its best to not use, Obviously having spent so much on a GPU I would rather not go blowing it up first day. I have been looking everywhere for a PSU that has all this but after so many hours of looking I am still coming up empty handed. If anyone could share some light on what to buy I would be forever grateful. Thanks :)

I feel I should add I am in the UK :( Thanks for the links though I appreciate your time and effort

a lot of cards use 12 pins, some use 14, and even a few use 16. I've built rigs with two cards that used 16 (two 8 pins) and my own has 12, and quite a few nvidia higher ups run 14. I've also used one that ran off 24 pins.. I really wish I actually owned that one. 525 watts of pure gaming performance.

Im not completely sure, that's a little confusing. I have a little computer knowledge but that make no sense to me :P Also I ideally need a 650w+

PSU I think a 600 watt PSU is recommended for that card. Edit: I just saw you are in the U.K. I'm not sure who sells computer parts there. Where did you buy your 770 gtx

I purchased it from Aria, we also have Ebuyer, amazon etc. That link looks good but Im just checking to make sure Im not certain. It has everything I believe but the 4pin for the motherboard? This is what im using Motherboard

In the details section on Newegg it is listed as main connector 20+4. That is what you need. On your link it lists: ATX Power connector (24-pin)

I suppose if you lot are as stumped as me, my second question would be is this safe to use instead? I have read around that its a bad idea, but no reason was ever given. I figured you computer savvy people might be able to elaborate :)

I've never used one, I'm not sure if it's safe or not. What PSU are you currently using?

The link I purchased it from doesn't work. Its just a generic, relatively cheap power supply, 650w

Do you have four free molex connectors to use two of those adapters?

I have the spare 6 pci-e, I just need the 6+2, so I only need the 2 molex, but Yeah I have them available :)

A splitter cable like that has nothing wrong with it in terms of ruining hardware, at least not a decent one. However it does decrease power efficiency by adding another length of cable which is why some people say to avoid it. Others because a power supply could balance improperly when running such wattage off of molex.

You should be fine running that connector if you already have a PSU you're set on using. Otherwise buy another PSU and save time and energy (literally saving power).

That is a great answer thanks! I shall use it for now then, and let my wallet recover before I attack it again. But I shall look into buying that GPU js93583 recommended. Thanks for your help all! :D

You are kinda lucky 'cause my father fried his PSU 2 weeks ago and we did some research.
Here some cheapish-but-good models:

They're all solid and they all have the connectors you required.

Oh wow thanks for the links! That fsp one looks like it would do the job! Shame its not a little stronger but I think that should suffice :D

Well, all of these have a bigger version. It's up to you to pick it, if you think you need it.

In any case, glad I could help.

It should be more than enough for you GPU though.

I see you are particularly worried about the 4-pin connector for the MB. Most recent PSUs have a 4+4 pin connector, meaning it's 2 cables running along, so you can use either 4 or 8, depending on your MB.
Similarly for the GPU you'll often see "6/8 pin" (or "6+2 pin") connector.

Do not buy adapters. Any decently branded (Corsair, Silverstone, XFX, etc.) 650W+ PSU should suit you fine, depending on what else you've got in your case.
If in doubt, get 750W.
