HI GUYS!!

I want to know if my psu can provide enough power for the pc and a HD 7770, the specs of my pc are:

cpu: phenom ii 555 unlocked and oc @ 3.665GHz at max vcore 1.5V
MB: asus m5a88 m
RAM: dual chanel 2X2 GB @ 1600 (1700 cose the oc)
storage: sata ii 750GB hard disc
other: two 12'' fan coller master @ 2000rpm, one operating all the time
PSU: thermal master 500 watts

now, this PSU suppose to be made by cooller master, but in the store, the guys told me that this psu is not a real watts, but in the legend of the psu has the numbers of the voltajes and currents, i did the math and it was like 495WATTS (and i know the dud psu's wile doing the math of the legend says a very different number that the one they say it suplys) more or less (if you want the data, tell me), it is the power it provides, doesnt?
also, if it is doesnt provide real watts, it must provide like 350W (i have done the math to)...

actually i find the PSU and you can help to check this out

i have done the math of the power consuption of my pc at full load in a page of coller master and it is like 280W i really dont remember well (i'll do it again to put the real number), so in fact it will be ok for a HD 7750 (like 55W), but a HD 7770 (like 80W) may won't work fine or even my psu will fail...

i want to buy a HD 7750 and i'm not such demanding gamer, but if for a few more bucks (pesos in my place XD) i can buy a 7770 may be i'll do.

and i'm in my work station right now, so i'll can write more details at home...

thanks a lot guys

I wouldn't trust that thing to not die and take other components with it. Get something else man.

As for the rated watts... I doubt it, but can't say for sure. Not a lot of info about them online, which isn't comforting.

That psu will make a great doorstop for someone. The 12v rail is rated at 20a which means you might get 220w out of it if it didn't burn up first.

Get a reputable power supply from corsair, antec, seasonic. 450w from a quality maker will give you all you need.

well some people is so afraid some times about the psu.... even the generic ones are safe protecting the rest of the parts of the pc if it is overloaded

in my case i'm sure if i overload this psu i just need to change it, i dont need to purchase something extra if i dont need it, for example: many of you must think in change this psu if OC the system... well i did it and the psu doesnt even warm a little and it works better than i thought sincerely

but by the other hand i think a HD7770 is too much for it... also i will sell this pc in two years may be.. so whts the point to buy a life warranty psu?? admit it those expensive brands are the same made in china garbage with a better warranty (and i know cose im an industrial engineer) all its just about marketing guys

so with the question... this thing bassed in the legend, could supplies, in principle the 500W it says??

(the generic ones says for example there are 500W psu's that in the legend doing the math just supplies 250, and they dont lie, at 275W they fail)

You're right - if you overloaded the psu and it failed, you would have to replace it. If, when it failed, it was not correctly protected, you would also be replacing one or more of the following: cpu, motherboard, gpu, and in some cases, whatever the resulting fire destroys.

It's your choice. You might want to read this

I personally vote for safety.

thanks a lot.... and i also from a third world country, so the quality of electricity sometimes is bad.
as a electrician technician too, as a labor for the comunity i have the need to tell that most of the psu in the world (and im the first who dont recomend a generic psu), when one psu fails, and its cose an overload, when this happends the capacitos blow up, and theres a diode that stops the danger (if the psu is a low end quality, and i mean the low end of the generics the chance to stop the danger is almost zero)... by the other hand if the protection fail, even the best quality ones had a chance to damage the pc, so all is about statistics, and thats why i want to know if my psu can supply my demand of power

so the real problem (in this cases) are the issues that come from the outside, for example a short cut, an over voltaje, power surges, etc... in this cases you have two options a high quality PSU, or just buying a an external power regulator (thats my case)...

so i already know about the risks, and if a had the money i just purchase a 2000W psu and problem solved, but thats not my case ): ok i'm exaggerating XD

but even with my experience, i dont really know if must trust in the legend, this PSU have a brand, if they dont deliver what they promise they will be in serius legal troubles, i think that things in the world wide works like that

and by the way the power consuption of my pc is like 293 at 90% of load, (i also put some extra charge on it) i dont know if my pc uses the 100%...

also watch this, in this case the psu says 500W, but in the legend the math is equal 250W, it is also overloaded until it blows up, and didnt damage the pc circuits

my psu doesnt submit any troubles 'till now, even with the OC, but if i have the chance i will change the psu for a descent 450W

I understand your position. You will have to make the final determination as to if your psu will suffice. If you are comfortable with diode protection and a fuse, then give it a go. I still think your psu is only about 220w effective, but again, your are more familiar with how things are done where you live.

Good luck and good gaming.

You only need 7 amps current rating on +12V to power a HD 7770. So that should give you 13 amps for OC.

But as others have mentioned, it's not a reputable PSU so if you can OC it without it blowing up, then it's good enough for me.

thanks alot guys...

at the begging i thought that this psu was a generic one like the most... but it really works fine, but i dont know how much can it handle, i'm sure that i will push a little with a hd 7750, but a hd 7770 i think could overload it

so for the guys who are searching anwers about this PSU, i can tell is not as bad as the most generic, and i still think that if it can handle the more or less 300W (the cpuid says that my phenom II consuption is like 160W) of my actual config it may handdle a little bit more than 350W safelly... i will meditate which GPU i will purchase and i will tell if this psu can handdle it

mark, ksham, max, thank for replay, i also will meditate who wrote what i can call a "solution"

I'm still attentive to suggestions

My one suggestion: get a PSU from a more reputable PSU manufacturer.

well there is no answer to my question... so i will find it out as a man of science XD

but with the time and with the money i will, cose it would be a good inversion, a good psu can be used for various pc's and i could sell this machine with my actual psu... i never thought in that before
