450w PSU GTX 770

[Space Kite]

Hi, I'm building a budge pc and I bought a Geforce GTX 770. My PSU says it's 450w.

Doing some research I've found that the GTX 770 has a power consumption of about 230W, but the thing is that the GPU has both 6-pin and 8-pin connectors. As far as I know the PCI-e Slot can deliver 75w and the 8-pin connector can deliver 150w = 225w (#math). Let's say my PSU only has an 8-pin connector, would it be enough for the GPU without the 6-pin connector?

I'm not planning to overclock or to put a lot of pressure on the graphics card, I'm only playing League of legends and some survival games from steam (Rust, Ark survival, 7 Days to die). Also Dota2 every now and then.

This is my first post. Thank you in advance for the information.

What PSU is it? 

[Juular]

Theoretically there should be enough power on single 8-pin but GPU may not power on without 6-pin and it's way more important which PSU is that model exactly than it's power rating. List your entire specs.

You wont find much information about this brand, since it's produced locally in mi country (I think). Here it is.

A mere 16 amps on the 12v rail, that thing would never cut it

The minimum I'd go for is a Corsair CX 450.

Ouch. Replace that pitiful thing ASAP. Where are you shopping at ?

I think I'll get this PSU http://us.coolermaster.com/product/Detail/powersupply/extreme-pp-psu/extreme-power-plus-550w.html

It's not very expensive and has all the connectors. (can't get rid of this underline now).

That's really old, can you not buy anything else?

 

Having all the connectors doesn't matter if the PSU isn't good 

[Space Kite]

Lol man you're killing me, Prob nay. What would you recommend that is not so old but also not so expensive?

What country are you from and what's your budget in local currency? That'll help a lot more given we are kind of basing this off of US prices.

[Space Kite]

Venezuela and my budged is 0$ right now XD but I might be able to make some money in the future.

[MrBrightSyde]

Given your country, I would say good luck to finding a reasonable PSU that isn't a time bomb. That CoolerMaster PSU seems a lot more reasonable given your circumstances

Would this be enough? it has one 4+4 pin power connector, I could use a Sata to 6pin or molex to 6pin power adapter. Any thoughts?

This thing are even more amusing lol, how the fuck there's 600W when there's supposedly two 12V rails for 22A total which is 264W, that plus another 140W from minor rails makes only 404W, where's other 200W ? What kind of math is that ?

Sell your 200W GPU OP, buy RX570 with some good PSU like at least Corsair CX450, it'll probably be cheapest decent unit available.

I had to "fish" my GTX 770 from ebay's used market, I literally spent about half an hour in the morning and half an hour at night searching for all the gtx 600 - 700 and 900 series cards for weeks... This was the best price-performance deal  I could find, just 49$.

By the way I've never had an issue with Aiteg PSUs I've used mine (the 450w one) for over 6 years without ever having an issue, I dismantle and clean it along with my whole computer atleast once every month. I usually put my hand in the back of my computer every day to check the air's temperature and the PSU is always fresh...

In order to ship things into my country safely one would have to use a courier, which is not cheap (3$ to 10$ for less than 5 pounds) and you have to pay it on top of the sellers shipping fee so selling it is not much of an option. The local economy is shit so selling it inside seems like too much of a stretch, the highest end cards you might encounter here in the used market wont get past the 500 series because anything over that is just too expensive to be bought from your average citizen.

 Could it be possible that the 12v n°2 is actually 14A + 14A? since it has two 4pin connectors.
that would make for 336 watts.
96 watts from 8A 12v n°1.
140 watts from minor rails.

336w + 140w + 96w = 572w

Or is this just wishful thinking. Any way I can check if this is true? I can dismatle the PSU and take photos.
 
 If this was true, the could it be that the 12V n°1 is also 8A x2  and it would actuallky be 692w? I've read somewhere that PSUs understate their actual capacity because reasons.

Att: wishful thinking Andy.

I have no idea how you ended up with that logic. 

 

No, don't take the PSU apart. You won't be able to get any more info from it, but you could electrocute yourself with 400V.

No.

Way more believable logic on how they could've ended up with this 600W rating is just multiplying it's real 300W rating (already dubious) by 2, you can see the model number, it's "300XE" guess what that number means.

Don't use it. It doesn't worth anything. These kinds of PSUs worth a dollar per piece and come with these Chinese 0.1mm metal cases as a bonus, you unscrew them and throw in the garbage, they're nothing more but decoration.
