Pros: Appears to be OEMed by ATNG (unconfirmed), the OEM responsible for numerous other good quality Rosewill branded PSUs. Build quality appears to be pretty good. I believe this is probably stepping in as the replacement for the "green" series from Rosewill. Works as intended. Provides safe, stable, reasonably clean power.. The Bronze efficiency rating seems to be on the conservative side, which is nice. The topology used is certainly capable of achieving very high efficiency. Sleeved cables is a nice touch at this price point.

Cons: 1x6pin and 4xSATA power is an artificial "clamp" placed on this PSU that more or less ensures it will always be used at half of its label rating or less. 2 X 6pin and 6 X SATA would have made the 450W ARC a stronger competitor. As it stands now, it's just a valid alternative to a CX430.

Overall Review: Middle tier component quality used throughout is expected at this price point. Chinese capacitors are from Teapo. The secondaries I can spot are 105C rated and are the same quality found in many other middle tier PSUs from OEMs like FSP and Delta. The component quality is probably the only thing holding the efficiency back from being a "gold" rated unit. Mosfet resistance being the primary issue.

Pros: Inexpensive

Cons: 90MB/s sustained write, 150MB/s sustained read speeds. The unit sent to review sites did 300-500MB/s. Bait-n-switch IMO.

Overall Review: There's nothing wrong with my system, that's the speed of the drive doing regular file transfers (big files). I have a Toshiba 19nm enterprise drive that does 500MB/s read/write speeds no problem on this same system. Sour taste in my mouth on this product from Kingston. I'm not going to fuss over it with them, I can live with the drive for $60, but buyer beware. This is a slow SSD by todays standards, very slow. (My 4 year old mechanical 7200rpm drive has better write speeds).

Pros: Fairly efficient out of the box. Very low idle power consumption. Can be tuned (underclocked/undervolted) to deliver 6650XT performance at 6600 power consumption but with very little fan noise. Can be tuned to deliver near-6700 XT performance with more power draw and noise. Backplate and bracket design is appropriately rigid to result in a no-droop install. Arrived pretty fast with free shipping, packaged well, installed easily. AMD driver installation tool did a clean removal and install of latest driver without any issues. Reasonably priced compared to historical trendlines for a ~300mm^2 GPU.

Cons: All RDNA architecture GPU's have significantly reduced performance in low-load conditions compared to older GCN architecture GPU's. Idling at near 0MHZ has consequences that you can feel. This GPU is a DOWNGRADE for scrolling, resizing, opening/closing tabs/windows, zooming, and video playback with scrolling and zooming in general applications and web browsers compared to much older GPU's. One of the primary reasons to buy a discrete GPU for a workstation is to maximize interactive performance, smoothness, and responsiveness. Modern AMD GPU's are actually a downgrade from integrated GPU's for a lot of basic application interface element acceleration. Sad.

Overall Review: I "upgraded" from an RX 480 and the computer feels less responsive and smooth for most general purposes. This GPU is only an upgrade when used for modern games. For all other uses it's worse than an old GPU. If you use your PC primarily for gaming, a modern GPU like this is great. If you use your PC for a fair bit of general productivity applications and web surfing I would advise sticking to older AMD GPU's with GCN architecture (300MHZ idle clock speeds), or modern Nvidia options that maintain 200MHZ+ idle clock speeds.

Pros: Newegg handled return and refund of this item painlessly.

Cons: The bad news.... This card is arriving DOA or failing prematurely or exhibiting problems for many people who buy it.

Overall Review: This is unfortunate, as ASRock's venture into the GPU market has been otherwise pretty positive, with most of their cards having very high initial reliability/performance/cooling/noise characteristics in their respective price classes. I would not hesitate to buy an ASRock GPU or motherboard, I've had very good luck with the brand overall and they consistently deliver great value. This particular batch of RX 550's has something wrong with it that slipped by QC. Avoid this particular GPU... For another 45 bucks or so an RX570 is in reach, may as well go that route. I originally purchased this as a video output device for a basic use small form factor machine, so really didn't care about the lower performance proposition here.

Pros: Fast for a mechanical drive. Sequential data rates as high as ~200MB/s. Reasonably quiet.

Cons: Failed self test with 10,000+ bad sectors and bad sector count growing rapidly after 2 years of use as a file storage/backup drive in a desktop computer that only gets used for very basic purposes like web browsing and media/entertainment. The actual I/O on this drive was minimal. Probably never even saw half of its total capacity written to it once.

Overall Review: Pass.

Pros: Bought 6 of these over 3 years ago and they have been running ever since. No failures and they are all still very quiet. The value is looking better and better with age.

Cons: The 4-pin molex connectors are a pain, as the pins usually just push out rather than make the connection, requires some meddling with a tool to press them into place.
